[Laszlo-user] Troubles with erasing previous elements on a, drawview

[Shishir Ramam]

Thanks Andre!
I also need a close path after every set of drawing moves.

I went back and looked at the documentation - and it still wasn't obvious to
me.
Gave me the mistaken impression that this is necessary only when one is
using primitives like 'lineTo'.

Not a complaint, but perhaps a small way in which the documentation can be
improved to make things a bit more obvious.

Thanks again for the help.
